Just days after the White House announced a community-based approach to combating terrorism in the United States, the FBI and other agencies are asking managers of surplus stores to spy on their customers, watching whether they pay in cash, make "extreme" religious statements or purchase products such as waterproof matches.

And the request from the government also is going to gun shops, fertilizer suppliers, motels and hotels, authorities say.

Earlier this month, the Obama administration announced a new plan titled "Empowering local partners to prevent violent extremism in the United States." In it, Obama wrote, "Communities – especially Muslim American communities whose children, families and neighbors are being targeted for recruitment by al-Qaida – are often best positioned to take the lead because they know their communities best."

The report warns that while the Constitution recognizes freedom of expression, "even for individuals who espouse unpopular or even hateful views," it also is the responsibility of government to deter "plots by neo-Nazis and other anti-Semitic hate groups, racial supremacists, and international and domestic terrorist groups."
